| Abstract | ||
| The addition of epoxy bending plate to the tension and compression faces or web is an effective technique for flexural or shear strengthening of reinforced concrete beams, also using of steel fibers with concrete improves the structural behavior and increases the moment capacity and shear resistance of the beams. General equations are derived for predicting the bending moment capacity, maximum and balancing reinforcement ratio the equivalent depth of the compression zone for singly and doubly reinforced rectangular sections and T-beams. The results indicate that bending moment capacity increased in beams with steel fibers and composite plates, while the maximum balancing reinforcement ratios are decreased. | ||
